For example, the nut member 104 is screwed into the tubular portion 110 in the cover portion 102. Further, the lock member 108 is disposed so as to be positioned at the lock release position in the stopper 120 of the cover portion 102.

  Next, the coil spring 106 is disposed between the nut member 104 and the tubular portion 110. Specifically, the second end 162 of the coil spring 106 is formed in the tubular portion 110 without locking the first end 160 of the coil spring 106 to the notch 142 of the nut member 104. Insert from the guide groove 118. The second end 162 of the coil spring 106 is guided and locked to the insertion groove 116 along the guide groove 118. Next, the first end 160 of the coil spring 106 is engaged with the notch 142 of the nut member 104. As a result, a rotational force in the direction approaching the stopper 120 (X-axis negative direction) is applied to the nut member 104 by the coil spring 106. The nut member 104 is moved away from the stopper 120 against the rotational force, the lock member 108 is lowered downward (Z-axis negative direction), and the connecting portion 182 is placed between the nut-side facing surface 146 and the stopper 120. To intervene. Thus, the assembly process of the cable support device 100 is completed.

  The work process for mounting the cable support device 100 that supports the cable 1 to the bracket 600 is as follows. First, the cable 1 is inserted into the through hole 112 of the cover portion 102 provided in the cable support device 100. Next, the nut member 104 is rotated in a direction away from the stopper 120 against the urging force of the coil spring 106, and the nut-side facing surface 146 of the nut member 104 and the stopper-side facing surface 124 of the stopper 120 are rotated. The distance between them is made longer than the width dimension of the connecting portion 182 of the lock member 108 in the front-rear direction (X-axis direction). In a state where the separation distance between the nut side facing surface 146 and the stopper side facing surface 124 is longer than the width dimension of the connecting portion 182, the lock member 108 is moved from the unlocked position to the locked position. Next, by releasing the hand from the nut member 104, the nut member 104 is rotated in a direction approaching the stopper 120 by the biasing force of the coil spring 106. As a result, as shown in FIGS. 1 and 2, the connecting portion 182 of the lock member 108 is sandwiched between the nut-side facing surface 146 of the nut member 104 and the stopper-side facing surface 124 of the stopper 120. At this time, the distance between the nut-side facing surface 146 and the stopper-side facing surface 124 is longer than the thickness dimension of the bracket 600. However, the distance between the guide portion 127 and the nut-side facing surface 146 of the nut member 104 is wider than the thickness dimension of the bracket 600.

  Next, the portion of the cable support device 100 between the nut-side facing surface 146 and the stopper-side facing surface 124 is inserted into the recess 610 of the bracket 600. In this process, as shown in FIG. 9, each facing portion 620 of the bracket 600 enters between the guide portion 127 formed on the stopper 120 and the nut member 104. Here, as described above, the distance between the guide portion 127 and the nut-side facing surface 146 is set wider than the thickness dimension of the bracket 600. Further, the guide portion 127 and the nut-side facing surface 146 move from the apex of the guide portion 127 (the boundary between the first inclined portion 127A and the second inclined portion 127B) to the lower side (the bracket 600 side). The distance between them increases in accordance with the inclination of the first inclined portion 127A. For this reason, each opposing part 620 is smoothly inserted between the guide part 127 and the nut side opposing surface 146 by being guided by the first inclined portion 127A.

  Next, the lower surface of the projecting portion 186 of the lock member 108 is pushed up while abutting against the upper surfaces of the pair of opposing portions 620 of the bracket 600, whereby the lock member 108 moves from the lock position to the lock release position. As a result, the lock member 108 does not intervene between the nut side facing surface 146 and the stopper side facing surface 124. As a result, the nut member 104 is rotated in the direction approaching the stopper 120 by the biasing force of the coil spring 106, and the bracket 600 is sandwiched between the nut side facing surface 146 and the stopper side facing surface 124 (see FIG. 10). ). At this time, the outer peripheral surface 149 of the nut side engaging portion 148 in the nut member 104 is locked to the inner peripheral surface of the mounting recess 612. Further, the outer peripheral surface 129 of the stopper side engaging portion 128 in the stopper 120 is locked to the inner peripheral surface of the mounting recess 612 (see FIGS. 6, 7 and 11). As described above, the cable support device 100 is attached to the bracket 600.

A-6. Effects of this embodiment:
As described above, in the cable support device 100 according to the present embodiment, the nut-side engagement portion 148 is formed in a part of the nut-side facing surface 146 of the nut member 104 in the cable circumferential direction. The nut-side engaging portion 148 has an arcuate outer peripheral surface 149 centered on the central axis of the tubular portion 110 when viewed in the cable insertion direction (X-axis direction). When the cable support device 100 is inserted into the recess 610 formed in the bracket 600, the nut-side engaging portion 148 can be disposed so as to be related to the inner wall surface of the recess 610 in the bracket 600 (see FIG. 6). ). As a result, according to the cable support device 100, the degree of rattling of the cable support device 100 with respect to the bracket 600 and the axial direction of the recess 610 of the bracket 600, compared to the configuration in which the nut member 104 is not provided with the engagement portion. The inclination of the cable support device 100 with respect to the can be reduced. Further, according to the cable support device 100, the nut-side engaging portion 148 is caused by a dimensional error between the nut-side engaging portion 148 and the recessed portion 610 of the bracket 600 as compared with the configuration in which the nut-side engaging portion 148 is formed over the entire circumference of the nut member 104. Thus, it is possible to prevent the nut-side engaging portion 148 from being inserted into the recess 610 of the bracket 600.

  In the cable support device 100, the length W1 in the cable circumferential direction of the nut side engaging portion 148 is longer than the separation distance W2 in the cable circumferential direction in the recess 610 of the bracket 600 into which the cable support device 100 is inserted (see FIG. 6). . For this reason, the cable support device 100 can be inserted into the recess 610 of the bracket 600 so that the nut-side engaging portion 148 is related to both the pair of facing portions 620 constituting the recess 610 in the bracket 600. As a result, according to the cable support device 100, the length of the nut-side engaging portion 148 is less than the separation distance W2 of the recess 610 of the bracket 600. The degree of sticking can be reduced more effectively. Further, since the opening side of the recess 610 in the bracket 600 does not come into contact with the cable support device 100, the cable support device 100 is likely to be rattled. Therefore, the nut side engagement portion 148 is associated with both the pair of facing portions 620. Is particularly effective.

  In the cable support device 100, a part (locking part) of the nut member 104 in which the nut side engaging part 148 is formed also serves as a part of the female screw 140. Further, in the nut-side facing surface 146 of the nut member 104, another portion (unlocked portion) different from the portion in the cable circumferential direction of the nut member 104 is formed on a portion of the nut member 104 of the female screw 140. The continuous portion is exposed (see FIGS. 5 and 6). As a result, according to the cable support device 100, the nut-side engaging portion can be achieved while reducing the size of the nut member 104 in the cable insertion direction as compared with the configuration in which the side of the nut member 104 facing the stopper 120 does not serve as the female screw 140. By using 148, the degree of rattling of the cable support device 100 with respect to the bracket 600 can be reduced.

  In the cable support device 100, a stopper side engagement portion 128 is formed on the stopper side facing surface 124 of the stopper 120. The stopper side engaging portion 128 has an arc-shaped outer peripheral surface 129 centering on the central axis of the tubular portion 110 when viewed in the cable insertion direction (see FIG. 7). The length W3 of the stopper side engagement portion 128 in the cable circumferential direction is longer than the length W1 of the nut side engagement portion 148 formed in the nut member 104 in the cable circumferential direction. Thereby, according to this cable support device 100, for example, compared with the structure where length W3 of stopper side engaging part 128 is less than length W1 of nut side engaging part 148, cable support device 100 of bracket 600 is compared. The degree of rattling or the like can be reduced more effectively.

  In the cable support device 100, at least a part of the nut side engaging portion 148 formed on the nut member 104 is located in the divided portion 128 </ b> A of the stopper side engaging portion 128 when viewed in the cable insertion direction (see FIG. 6). . For this reason, the degree of rattling of the cable support device 100 with respect to the bracket 600 caused by the divided portion 128 </ b> A of the stopper side engagement portion 128 is suppressed by the nut side engagement portion 148 formed on the nut member 104. Thus, according to the cable support device 100, the degree of shakiness of the cable support device 100 with respect to the bracket 600 compared to a configuration in which the nut-side engaging portion 148 is not located at the divided portion 128A of the stopper-side engaging portion 128. Etc. can be reduced more effectively.

  In the present cable support device 100, the guide portion disposed at the stopper 120 at a position on at least one side in the horizontal direction with respect to the tubular portion 110 and facing the nut member 104 in the cable insertion direction. 127 is formed (see FIG. 8). The guide portion 127 includes a first inclined portion 127A. 127 A of 1st inclination parts incline so that it may distance from the nut member 104 as it goes to the one side (lower side) of an up-down direction. For this reason, when the cable support device 100 is inserted into the recess 610 formed in the bracket 600, the tip portion (opposing portion 620) constituting the recess 610 is guided by the first inclined portion 127A of the guide portion 127. As a result, the distal end portion of the bracket 600 is smoothly inserted further into the back side between the nut member 104 and the stopper 120. Thus, according to the cable support device 100, the distance between the guide portion 127 and the nut side facing surface 146 is uniformly the same as the distance between the apex of the guide portion 127 and the nut side facing surface 146. In comparison, the insertion property (ease of insertion) of the cable support device 100 into the recess 610 of the bracket 600 can be improved.

  In the cable support device 100, the guide portion 127 further includes a second inclined portion 127B. The second inclined portion 127B is inclined so as to move away from the nut member 104 from the upper end of the first inclined portion 127A toward the upper side (see FIG. 8). Thus, according to the cable support device 100, for example, the guide member 127 is different from the nut member 104 in comparison with a configuration including a flat portion extending in a direction parallel to the nut member 104 from the end of the first inclined portion 127A. Since the contact resistance between the bracket 600 interposed between the stopper 120 and the guide portion 127 is small, the cable support device 100 can be smoothly inserted into and removed from the concave portion 610 of the bracket 600. Further, according to the cable support device 100, the guide portion 127 has neither the second inclined portion 127B nor a flat portion, and the first inclined portion 127A has an acute angle compared to the configuration in which the first inclined portion has an acute angle. It is reinforced and the insertion property of the cable support apparatus 100 to the recessed part 610 of the bracket 600 can be improved.

  In the cable support device 100, the second inclination angle θ2 of the second inclined portion 127B with respect to the nut member 104 is smaller than the first inclination angle θ1 of the first inclined portion 127A with respect to the nut member 104. Thereby, according to this cable support apparatus 100, compared with the structure whose 2nd inclination | tilt angle (theta) 2 is equivalent to or more than 1st inclination | tilt angle (theta) 1, for example, between the nut member 104 and the 2nd inclination part 127B. The gap between them becomes narrower. As a result, it is possible to improve the resistance against the force with which the cable support device 100 tries to come out of the bracket 600, and to reduce the degree of rattling of the cable support device 100 with respect to the bracket 600.

  In the cable support device 100, the position of the upper end of the first inclined portion 127A (that is, the position adjacent to the first inclined portion 127A and the second inclined portion 127B) is the central axis of the tubular portion 110 in the vertical direction. Is the same position. Thereby, according to the cable support device 100, for example, there is no undercut portion as compared with a configuration in which the position of the upper end of the first inclined portion 127A is different from the central axis of the tubular portion 110 in the vertical direction. Therefore, the main body can be easily manufactured by die cutting.
